28 CFR 16.23: General disclosure authority in Federal and State proceedings in which the United States is a party.

(a) Every attorney in the Department of Justice in charge of any case or matter in which the United States is a party is authorized, after consultation with the “originating component” as defined in § 16.24(a) of this part, to reveal and furnish to any person, including an actual or prospective witness, a grand jury, counsel, or a court, either during or preparatory to a proceeding, such testimony, and relevant unclassified material, documents, or information secured by any attorney, or investigator of the Department of Justice, as such attorney shall deem necessary or desirable to the discharge of the attorney's official duties: Provided, Such an attorney shall consider, with respect to any disclosure, the factors set forth in § 16.26(a) of this part: And further provided, an attorney shall not reveal or furnish any material, documents, testimony or information when, in the attorney's judgment, any of the factors specified in § 16.26(b) exists, without the express prior approval by the Assistant Attorney General in charge of the division responsible for the case or proceeding, the Director of the Executive Office for United States Trustees (hereinafter referred to as “the EOUST”), or such persons' designees.

(b) An attorney may seek higher level review at any stage of a proceeding, including prior to the issuance of a court order, when the attorney determines that a factor specified in § 16.26(b) exists or foresees that higher level approval will be required before disclosure of the information or testimony in question. Upon referral of a matter under this subsection, the responsible Assistant Attorney General, the Director of EOUST, or their designees shall follow procedures set forth in § 16.24 of this part.

(c) If oral testimony is sought by a demand in a case or matter in which the United States is a party, an affidavit, or, if that is not feasible, a statement by the party seeking the testimony or by the party's attorney setting forth a summary of the testimony sought must be furnished to the Department attorney handling the case or matter.
